O. R. BALL FORCE OILER June 3, 1930.

Filed June 17, 1929 afzmdadgm Patented June 3, 1930 UNITEDv STATES PATENT OFFICE FORCE OILEB Application led .Tune 17,

My present invention has reference to an improvement in oil cans and the primary object thereof is the provision of a simple and positive oiler which may be cheaply constructed and in which the parts constltuting the same are detachably associated.

A further object is the provision of an oil can having a chamber at the bottom thereof forming the pressure chamber from which oil is forcibl expelled into the spout and directed theret rou h when pressure is applied to the bottom of t e can.

A still further object of the invention is to provide a can having a pressure chamber' at the bottom thereof, together with valve controlled means for admitting oil from the can into the chamber, said chamber having a tube extending from the top thereof which is connected to the outlet spout for the can and which tube has its passage controlled by a normally seated spring influenced valve, which valve, however, is unseated when pressure is exerted'upon the bottom of the can, such pressure forcibly ejecting the oil therefrom through the spout of the can and such pressure also closing the inlet valve to the chamber, so that only a determined quantity of oil will be ejected from the can upon the compression of the bottom thereof, the device being also provided with a suitable air inlet.

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

In the drawings:

Figure 1 is a substantially central sectional longitudinal view through a force oil can in accordance with this invention.

Figure 2 is a side elevation with the parts constituting the improvement disassociated.

Figure 3 is a side elevation of a goose neck tube provided with the valve that affords the oil entrance to the compression chamber.

Figure 4 is a sectional view on the line 4-4 of Figure 1.

As disclosed by the drawings my improvement includes a can 1 that has screwed in the reduced mouth thereof a closure 2. The closure is provided with an opening that affords an air inlet 3. There is screwed through the closure the reduced tubular end 4 of the out- 1929. Serial No. 371,568.

let spout 5. The wall or shoulder provided between the spout 5 and the tubular extension at the end thereof is received in a depression in the closure 2.

The bottom of the cam is open and is provided with exterior threads. On the bottom of the can there rests a gasket 6 and against the gasket there is arranged the straight lower edge 9 of the upper and convex disc 10 that provides the upper element of the compression chamber. There is passed centrally through the disc 10 a tube 11 and this tube is threaded to be engaged by nuts 12 and 13 which contact with the opposite faces of the disc or upper wall 10 of the `compression chamber. The tube 11 has screwedor otherwise secured on the end thereof a larger tube or pipe member 14 in which the tube 4 of the spout 5 is received. The end of the tube 4 is spaced a suitable distance from the tube 11 and this space has arranged therein a helical spring 15 which contacts With the ball valve 16 to force the same partly into the upper end of the tube 11 to close the said tube.

. To one side of the centrally arranged tube 11 the upper convex wall of the compression chamber receives therethrough the straightf branch 17 of a goose neck pipe or tube 18. The outer portion of the goose neck pipe 18 is downwardly directed and has screwed thereon a substantially cup-shaped cage 19 for a ball valve 20. The cage 19 except for the opening at the center thereof that aifords a seat for the valve 20 is closed. The straight branch 17 of the goose neck shaped tube is engaged by inner and outer nuts 21 and 22, respectively, that contact with the inner and outer faces of the disc or upper wall of the compression chamber.

Contacting with the edge of the disc 9 there is an outwardly bowed spring 23 and this spring exerts a pressure against the outwardly concaved wall of the flexible bottom 24. The concaved and flexible bottom 24 is formed on the inner face of a ring flange 25, and the said ring flange is screwed on the bottom of the can 1 and compresses the disc 10 and gasket 6, as well as the outer edge of broad spring 23 between the outer end of the can 1 and the portion of the flexible bottom 24 that is connected with the ring flan e 25. When the rin flan e 25 is screwed on t e can the disc 10 is eld rom turning through the medium of a pin 26 which is fixed thereon and which is brought into contact by a lug 21 formed on the can 1. The space between the oppositely rounded discs 10 and 24 provides a compression chamber which for dlstmction is indicated in the drawings by the numeral 28.

By removing the closure 2 the spout 5 and its tubular extension 4 may be readily withdrawn from the can 1 so that the said can may be filled with oil. The weight of this oil will unseat the valve 20 so that a certain quantity of the said oil will flow into and fill the compression chamber 28. The spout and closure are again positioned on the can so that the tubular end 4 of the said spout Will be received in the ipe or tubular member 14. The spring 15 will? of course, force the valve against the mouth to close the passage through the tube 11. A pressure upon the flexible bottom 24 of the improvement will force oil from the compression chamber 28 through the tube 11, causin the same to unseat the valve 16 and forci ly eject 'the oil through the tube 14 and through the spout 5. Only a determined quantlty of oil will be ejected at each depression of the bottom 24 of the can and when the bottom is depressed the compression in the chamber 28 will cause the valve 20 to be seated on the Wall of the opening of the cap member which I have termed the cage 19. From the foreoing description it will be noted that all of t e parts constituting my improvement are of a simple nature which may be easily connected and disassociated. The intake and outlet valves connected with the disc 10 are first associated in the can and thereafter the ring carrying the compressible disc or bottom of the can is screwed onto the said can. The closure2 and the spout 5 may be there- `a-fter connected to and arranged in the can 'a's disclosed by the'drawings. f Y2" The intake valve is arranged near the iliv ner and false bottom 10 of the can but is disposed above the compression chamber 28 and an overflow of oil in said compression chamber entering the goose neck tube 18 will closethis valve, so that only a determined quantity of oil will be received in the chamber whether or not the can device is operated by the compression of the concaved or disclike flexible bottom 2A. Itis believed the construction and advantages of the improvement will be apparent to those skilled in the art to which such invention relates and that further description will not be required, although I do not wish to be restricted to the precise details herein set forth and, therefore, hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim.
